For night owls who don’t want to wake a sleeping partner, this window-shaped LED reading light is indispensable. I’ve been using the wedge for ten years, turning pages into the wee hours without rousing my husband.

While most reading lamps shed ambient light, the wedge illuminates the page with a bright, diffuse but localized light panel. It would be as handy in a darkened theater as in bed. My model is battery powered (the 2.0 is rechargeable), but I haven’t had any need to replace them quite yet.
